Hi there!

I'm trying to build my workspace with only hector_slam package inside in my new raspberry pi 3 with this http://www.german-robot.com/2016/05/2... OS (suggested by the ROS team) but every time I do catkin_make it freezes in differents %. Here you have the commands I already tried.

catkin_make catkin_make -j1 catkin_make_isolated

May be one of you can help me trying to build this workspace.

ROSBAG HECTOR-SLAM Hi guys, I'm trying to record a hector-slam map with rosbag and then trying to reproduce it. The thi

Hi guys,

I'm stuck here now,

I have this common listener with a subscriber:

def listener():
    rospy.init_node('teleop_list', anonymous=True)

    rospy.Subscriber('key_vel', Twist, callback)

    # spin() simply keeps python from exiting until this node is stopped
    rospy.spin()

I want to know if there is a way to call the callback when no data is received (I already know the callback theory, when something happens the callback is triggered, and this is why I'm asking) or find a way to do something while the callback is not triggered

Ty

I got it, with some mods but thank you!!!

the thread is called the same time with the Subscriber def callback(data): # def listener(): #do smt def ma

yeah, after think a bit and read the whole stackoverflow post I think i get it. Thank you!

I can't imagine how can I connect what you are saing with the rospy.Subscriber. I have this: def callback(data): #d

hector navigation Hello guys, Im trying to install hector navigation from source cloning https://github.com/tu-darmstad

Hi @bxl, did you install hector_navigation?

It works! Thank you!

Hello guys!

My question is quite simple, i have been searching for 2 days and i couldn't find the answer.

I'm building my own robot, using RPi3 with a RPLidar and SLAM for mapping. How can I see the position of the robot (I can see the data and the map, but not where my robot is) , or at least the frame in the RViz output? I tried whit a lot of configs in the RViz control panel and nothing happend.

Here is the launch file I'm using right now.

<!--
  Used for visualising rplidar in action.

  It requires rplidar.launch.
 -->
<launch>
  <include file="$(find rplidar_ros)/launch/rplidar.launch" />
  <include file="$(find rplidar_ros)/launch/hectormapping.launch" />
  <node name="rviz" pkg="rviz" type="rviz" args="-d $(find rplidar_ros)/rviz/slam.rviz" />
</launch>

Tyy!!

This is what I am needing, I will find the way to do it. TY.
